VRA1205YMD-6WR3 产品概述

一、产品简介

VRA1205YMD-6WR3 是 YLPTEC(易川) 推出的一款 6W 双路隔离式直流/直流电源模块,输入采用 2:1 宽电压设计(9V~18V),典型转换效率可达 84%。模块体积紧凑,封装为 DIP,尺寸 25.4 × 25.4 × 11 mm,适合在空间受限的嵌入式系统中使用。裸机通过 CISPR32/EN55032 Class A 测试,适用于医疗、工控、仪器仪表、通信与轨道交通等对可靠性与隔离要求高的场合。

二、主要性能参数

  • 输出通道:2 路
  • 输出电压:±5V
  • 输出电流(单路最大):600 mA
  • 输出功率:6 W(总)
  • 输入电压范围:9 V ~ 18 V(2:1 宽范围)
  • 隔离电压:1500 VDC(等同 1.5 kVrms)
  • 典型转换效率:84%
  • 开关频率:250 kHz
  • 纹波噪声:50 mVpp
  • 最大容性负载:1100 µF
  • 待机功耗:约 0.3 W(典型)
  • 外形尺寸:25.4 × 25.4 × 11 mm(DIP)

三、保护与可靠性

模块具备多重保护机制,提升系统安全性与可靠运行能力:

  • 输入欠压保护:防止输入供电下降导致异常工作
  • 输出过压保护:保护后级负载与器件
  • 输出过流/短路保护:支持自动恢复或恒流限制以应对短路情况
  • 工作温度范围:-40 ℃ ~ +85 ℃,适应严苛环境
  • 隔离性能良好,满足工业及医疗类系统对隔离的要求

四、封装与热管理

  • 封装类型:DIP,便于插装和波峰/回流焊接的板上安装
  • 尺寸与紧凑性适合模块化设计,但在高负载或高环境温度下需考虑散热与热降额;建议在 PCB 布局时预留散热通道并配合合适的通风或散热铜箔。

五、典型应用场景

  • 医疗设备:隔离电源为弱信号测量与人体安全提供必要保护
  • 工业控制:驱动传感器、控制器及隔离信号链
  • 仪器仪表:为精密测量电路提供低噪声、稳定电源
  • 通信与铁路:在需稳定隔离供电的通信设备与轨道系统中应用

六、使用建议与注意事项

  • 输出端建议使用低 ESR 电容进行滤波以降低纹波,注意单路容性负载不超过 1100 µF;
  • 在高温或高负载工况下,应考虑功率降额与额外散热措施;
  • 输入侧建议并联适当的滤波与浪涌抑制元件以提高系统抗干扰能力;
  • 模块虽有多重保护,但在系统设计中仍应配合外部保护(如保险丝、过压吸收)以提高整体可靠性。

VRA1205YMD-6WR3 以其高效率、宽输入范围、良好隔离与多重保护,适用于对体积、效率与可靠性都有较高要求的工业与医疗级别电源解决方案。若需详细规范书、曲线或典型接线图,可联系供应商获取完整数据手册。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
